PAPER-CARTRIDGE CRIIVIPER.

SPECIFICATION forming part of Letters Patent No. 566,126, dated August18, 1896.

Application filed January 15, 1896. Serial No, 575,583. (No model.)

To all whom it may concern:

Beit known that I, JOHN H. BARLOW, a citizen of the United States, and aresident of New Haven, in the county of New Haven and State ofConnecticut, have invented certain new and useful Improvements in Paper-Cartridge Crimpers, of which the following is a specification.

My invention relates to new and useful improvements in paper-cartridgecrimpers, and particularly to that class of implements designed to turnover inward the end of the Shell, and to tightly iron such turned-overportion firmly against the inner walls of the shell and at the same timepress the end of the turned-over portion firmly against the wadding,thus preventing it from spreading over the surface of the wad andweakening the resistance against the action of the explosive force,which would impair the velocity of the shot.

It is the object of my invention to provide a crimper that can be usedupon a lathe or any suitable crimping-tool which has a bore of a properdiameter to accommodate the sha-nk of said crimper.

It is further an important obj ect to provide simple and durable meanswhereby a single implement may be made to accommodate different sizes ofshells by providing said crimpers with different sizes of ironers andcrimping-heads.

There are at this time in general use what are known as insideironers,the diameter of which is determined by the space required tohold the turned-over portion of the shell between the inner diameter ofthe shell and the outer diameter of the ironer. Thus each and everydifferent size of shellrequires a different and specific size of ironer,which has necessitated thus far the manufacture of a separate andcomplete implement for each and every different size of shell. (Toenumerate, ten, twelve, fourteen, sixteen, or twenty gage, the.) Asthese are many, the expense to users is great, they being compelled topurchase so many different implements.

I-Ieretofore the cylindrical shank or crankshaft, to which power isattached and to which the crimping-head is fastened, has been made withthe inner chamber or recess conforming to the size of the outer diameterof the ironer required for each of the several sizes. No one size couldbe interchanged with the other, as each size of ironer is of a differentdiameter, as set forth above. To overcome this dificulty, I make theshanks to which the heads are attached of exactly the same outsidedimensions and the holes of exactly the same diameter, or, in otherwords, the shank is the same inside and out for all gages. I am able todo this by giving two diameters to the ironers, as follows: the rear endof all sizes to be the same, which shall be a sliding iit into the holeof the shank. The forward end of the ironers are to be of the specificsize required for each gage, the threaded portion of the shank and thethreaded portion of the various crimpingheads to be all of the samediameter and pitch, the end of all the ironers to be slotted, as shown.

Upon the accompanying drawings, which form a part of this specification,the same reference -characters denote like or corresponding parts uponthe several figures, and of which- Figure l is a side elevation of mynovel crimping-tool, the driving connections therefor being omitted.Fig. 2 is a front end elevation of Fig. l. Fig. 3 is a central Verticallongitudinal section. Fig. Lis a similar central vertical longitudinalsection of a slightlymodied form. Fig. 5 is an end View of theconstruction shown in Fig. 4. Fig. 6 shows a vertical longitudinalsection of the head and a plan and end View, respectively, of aslightlymodified form of ironer. Fig. 7 is a similar verticallongitudinal section of a head and plan view of the ironer shown in Fig.4.

Referring to the reference-characters upon the several gures of thedrawings, A indicates the shank or holder, which is cylindrical in formand adapted to be used as a lathe crimping-tool, which are now made as adistinct article of manufacture, or it may be used in connection with acrimping-tool such as is shownlin my former patent, No. 553,024, ofJanuary 14C, 1896. This shank is provided with two distinct peripheralsurfaces l and 2, the former serving as a bearing or spindle and thelatter as means for attaching power mechanism, such as a crank ordriving-wheel. Within this shank Iprovide a bore 3,to accom- IOO modatea spiral spring 4, which serves lto yieldably retain the ironer inposition; The inner end of the surface l is threaded to engage internalthreads of the detachable heads B.

The heads iB are made in different sizes, all of which are provided withan internal threaded surface 5 of a uniform size to admit of the readyattachment of the threaded shank. They are further provided with theusual recess 6 to receive the shell to be ironed, and the pins 7,adapted to engage and turn in said shell. Also an internal rib 8 isformed within the head and serves to engage the shoulder of the ironer,thus retaining the same against the action of the spring 4.

The ironers C are made in dierent sizes to iit the heads abovementioned, their inner ends 9 being larger than their outer ends 10,thus forming a shoulder 1l, which is firmly retained against the rib ofthe head by the action of the spring 4 within the shank. The ironer isfurther provided with a longitudinal slot 12 in the top thereof toaccommodate a screw 13, fitted within the shank, having itsv endextending into said slot, thus preventing said ironer from having anyindependent rotary motion, at the same time allowing it a freelongitudinal movement.

In the construction shown in Figs. 4, 5, and 7 I have shown anironerwhose operative end is equal to or larger than its inner end, andI provide one or more grooves 14 in said outer end, forming shoulders 11to receive the end of one of the pins 7, which are longer than the pinsshown in the above figures, andI serves as a means for retaining saidironer in position.

It will be obvious from the above that it is immaterial as to the sizeof the outer operative end of the ironer so long as the same conforms tothe size of the head, which is made of a certain gage, yet it isimportant that the inner end of said ironers should be of a uniformdiameter to admit of the various sizes of ironers being usedinterchangeably.

It will be seen that my construction of the shank, as described andshown by me, is of great value to the manufacturer, for instead of, asnow, making a complete implement for each separate gage all frames andall shanks are alike. They are one and the same for all gages,dispensing with the necessity of sepai this construction the shanks aremade inl quantities all alike, from which may be filled orders for anygage of lathe crimping-tools. The same may be taken and inserted in theframes common for all; also the same may be used for the power-crimperby attaching the driving-wheel. Thus immense saving is apparent.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, is-

1. In a cartridge-crimper of the class described, the combination with ashank having two distinct peripheral dimensions and a bore centralthereof, of a detachable head secured to said shank, an ironer fittedlongitudinally within said head and provided with two distinctdiameters, forming a shoulder to be engaged by said head, and wherebythe same is retained in position, substantially as described.

2. In a cartridge-crimper of the class described, a shank having a bore,a head detachably secured to said shank, an ironer having two distinctdiameters and suitable means for retaining the ironer yieldably in placein the shank, whereby said ironer is made interchangeable for variousgages of cartridges, substantially as described.

Signed at New Haven, in the county of New Haven and State ofConnecticut, this 9th day January, A. D. 1896.
